“…PALS can give not only the size of free volume, but also the distribution of free‐volume cavities . The lifetime τ 3 and its relative intensity I 3 are related to the average free volume radius and free volume cavity quantity of polymer blends, respectively . These results are shown in Table and Figure .…”

Supertough polylactide (PLA)/polyurethane (PU) blends were prepared by reactive blending of PLA with polyester polyol and toluene‐2,4‐diisocyanate. The free volume and interfacial compatibility between the two polymers were investigated by positron annihilation lifetime spectroscopy. The PU particles dispersed homogeneously in the PLA matrix and self‐assembled into a subinclusion microstructure, resulting in fibrils and significant plastic deformation occurs during impact process. More phase interface and free volume cavities formed between PLA and PU boundary because of a good interfacial compatibility between the two polymers, leading to smaller sizes of free volume cavities, and the increasing of the number of these cavities. Therefore, the toughness of PLA was greatly improved by blending PU. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46596.

“…A more detailed analysis of this cure curve, along with the comparison of its characteristic times and torques, is important and can be performed from a theoretical and experimental approach . In such references, the use of kinetic models is described, as well as the simulation of a rheometer curve using a few parameter data, fitting the curve with parabolic and hyperbolic functions.…”

In order to find the best combination of three synthetic rubbers, that is, styrene‐butadiene rubber (SBR) grade 1712, SBR grade 1721 and high‐1,4‐cis polybutadiene, that produce a compound with specific end‐use properties, a statistical experimental design is proposed in this work. The design consists of ten mixtures containing specific amounts of total styrene and BR content. A number of properties are tested in each mixture, selecting those related to requirements for the tread of a high performance tire: glass transition temperature (Tg), the ratio between the viscous modulus and the elastic modulus (tanδ@60 °C), Mooney viscosity, and the tensile properties. The values obtained for each property are fit to statistically significant models, obtaining the respective response surfaces. These are next used to define a desirable formulation with the optimal ratio of each rubber, and finally the optimized formulation is validated by comparing the experimental and predicted values for each modeled property. © 2018 Wiley Periodicals, Inc.

“…Swelling measurement was conducted based on ASTM 471. The compression molded samples were cut with dimension (2 x 2 x 2) mm 3 and weighed and immersed in toluene at room temperature for 24 hours before the first reading was taken. The weight of the sample was recorded until the reading reached an equilibrium state.…”

Hybridization of silanized CB/PCC filler reinforced NR/SBR blends was prepared on a two roll mill. The si-CB/PCC composites were vulcanized via a conventional sulphur system at 180 o C. The primary aims of this research are to scrutinize the effects of different concentration of si treated hybrid CB/PCC fillers ranging from 2 wt. % to 10 wt. % on the NR/SBR blends properties towards the curing characteristics, viscosity and crosslink density. In this work, a positive correlation was found between silane content on the hybrid filler surface and NR/SBR blend properties. It was found that at 6% of Si 69 concentration (F4) provided improvement in crosslink density and mooney viscosity properties. Increment of crosslink density in the blends would increase the viscosity and it may be due to the network formation between the treated fillers and rubber molecules. Moreover, the incorporation of treated fillers accelerates the curing process due to the surface activation and hence leads to tightly contact between filler-rubber phases.
